1. The growth rate equation has a general form of:
y = A (r)^t
The function is growth when r≥1, and it is a decay when
r<1. Therefore:
y=200(0.5)^2t -->
Decay
y=1/2(2.5)^t/6 -->
Growth
y=(0.65)^t/4 -->
Decay
2. We rewrite the given equation (1/3)^d−5 = 81
Take the log of both sides:
(d – 5) log(1/3) = log 81
d – 5 = log 81 / log(1/3)
d – 5 = - 4
Multiply both sides by negative 1:
- d + 5 = 4
So the answer is D
I can tell this activity is about graphing, but the writing is barely legible, can you re-upload the pictures or write it out?
The number of hours required for 3 tractors to plow the field is 2.4 hours
<em><u>Solution:</u></em>
Given that 5 tractors can plow a field in 4 hours
We have to find out number of hours required for 3 tractors to plow the field
5 tractors can plow a field in 4 hours, So time taken for 1 tractor
<em><u>So time taken for 3 tractors is given as:</u></em>
time taken for 3 tractor = time taken for 1 tractor x 3
So number of hours required for 3 tractors to plow the field is 2.4 hours
Answer:
1. b d
2. is c or d
3. a or c
4. b or c
5. c
Step-by-step explanation:
The literal equation for x is g/4+5y
<h3>Subject of formula</h3>
This is a way of representing a variable in terms of another
Given the equation below;
g=4x+5xy
Factor out x to have
g=x(4 + 5y)
Divide both sides by 4 +5y to have:
g/4+5y = x
x = g/4+5y
Hence the literal equation for x is g/4+5y
